Outcome Measures

Primary Outcomes (3)

  • Direct medical expenses

    Direct medical expenses refer to the expenses incurred by patients and/or their families for medical and health services related to Alzheimer's disease

    baseline

  • Direct non-medical expenses

    The direct non-medical costs of Alzheimer's disease include care costs, home facilities and repair costs, health care products costs and related expenses incurred during medical treatment. The cost of care includes the salary of caregivers, the expenses of external caregivers, and the travel expenses of caregivers

    baseline

  • overhead expenses

    Indirect costs include the economic loss caused by patients' inability to work, the decrease in the income of informal caregivers, the treatment expenses of caregivers' psychological diseases and the medical expenses incurred by patients with Alzheimer's disease or caregivers due to accidental injuries.

    baseline

Study Arms (3)

amnestic mild cognitive impairment(aMCI)

1. aMCI diagnostic criteria of National Institute of Aging and National Association of Alzheimer's Disease (NIA-AA). 2. The ClinicalDementiaRating scale (CDR) is 0.5. 3. Mini-MentalStateExamination (MMSE): MMSE≥17 for those with 0 years of education, ≥20 for those with less than 7 years, and ≥24 for those with more than 7 years. 4. Memory impairment is prominent, and it may also be accompanied by functional impairment of other cognitive domains. 5. The onset is insidious and the progress is slow. 6. Not up to the level of dementia

Other: There was no intervention as this was an observational study.

mild to moderate AD

Clinical dementia rating (CDR) was used to assess and determine the degree of cognitive impairment of the patients, according to the CDR score, where the mild AD group with a CDR score of 1, and the moderate to severe AD group with a score of 2 to 3.

Other: There was no intervention as this was an observational study.

severe AD

Clinical dementia rating (CDR) was used to assess and determine the degree of cognitive impairment of the patients, according to the CDR score, where the mild AD group with a CDR score of 1, and the moderate to severe AD group with a score of 2 to 3.

Other: There was no intervention as this was an observational study.
